COVID-19 was already in the U.S. by December 2019, study says

Testing has found Covid-19 infections in the U.S. in December 2019, according to a study, providing further evidence indicating the coronavirus was spreading globally weeks before the first cases were reported in China.

The study published Monday identified 106 infections from 7,389 blood samples collected from donors in nine U.S. states between Dec. 13 and Jan. 17. The samples, collected by the American Red Cross, were sent to the U.S. Centers for Disease Control and Prevention for testing to detect if there were antibodies against the virus.

“The findings of this report suggest that SARS-CoV-2 infections may have been present in the U.S. in December 2019, earlier than previously recognized,” the paper said.
